Configuring Sandboxes

A sandbox is configured in a sandbox.toml file in the root of your app directory. It points to a Terraform module (public or private repo) and passes variables to configure the infrastructure.

Basic Configuration

sandbox.toml

terraform_version = "1.11.3"

[public_repo]
directory = "."
repo      = "nuonco/aws-eks-sandbox"
branch    = "main"

[vars]
cluster_version = "1.33"
cluster_name    = "n-{{.nuon.install.id}}"

enable_nuon_dns      = "true"
public_root_domain   = "{{ .nuon.inputs.inputs.root_domain }}"
internal_root_domain = "internal.{{ .nuon.inputs.inputs.root_domain }}"

[[var_file]]
contents = "./sandbox.tfvars"

sandbox.tfvars

additional_namespaces = ["grafana"]

min_size = 2
max_size = 3
desired_capacity = 2

You can use either a public repo (public_repo block) or a private GitHub repo (connected_repo block). Read more about VCS configuration here.

Using Default Values

Add a vars block to sandbox.toml or use the sandbox.tfvars file for default values shared across all installs:

sandbox.toml

[vars]
cluster_name         = "n-{{.nuon.install.id}}"
enable_nuon_dns      = "true"
public_root_domain   = "{{ .nuon.install.id }}.nuon.run"
internal_root_domain = "internal.{{ .nuon.install.id }}.nuon.run"

[[var_file]]
contents = "./sandbox.tfvars"

Using Inputs

Define an input in inputs.toml and reference it in sandbox.toml:

inputs.toml

[[group]]
name         = "dns"
description  = "DNS configuration"
display_name = "DNS"

[[input]]
name         = "root_domain"
description  = "The root domain for the install."
default      = "app.example.com"
display_name = "Root Domain"
group        = "dns"

sandbox.toml

[vars]
public_root_domain = "{{ .nuon.inputs.inputs.root_domain }}"

Sandbox Outputs

Sandbox outputs are accessible to all components through variables:

components/app.toml

[values]
account_region = "{{.nuon.install.sandbox.outputs.account.region}}"

Common outputs include:

account.id - The AWS Account ID
account.region - The AWS Region
vpc.id - The VPC ID
cluster.cluster_name - The EKS Cluster name
cluster.cluster_endpoint - The EKS Cluster endpoint
ecr.repository_url - The ECR repository URL
nuon_dns.public_domain - The public root domain
nuon_dns.internal_domain - The internal root domain
namespaces - Namespaces created in the cluster

See the outputs.tf for the full list.

Custom Sandboxes

You can fork a managed sandbox or create your own. Point your sandbox.toml to your repo:

sandbox.toml

terraform_version = "1.11.3"

[public_repo]
repo      = "your-org/your-sandbox"
directory = "sandbox"
branch    = "main"

If you are considering a custom sandbox, we would love to hear about your use case. Please contact us.
